X-Planes. The era of experimental supersonic aircraft - or "X-planes" - made heroes out of the test pilots who risked their lives to conduct all-important live research. Featuring rare archival footage, this program examines the evolution of X-planes, showing you Nazi Germany's Me 163, the Bell X-1 and Chuck Yeager's attempt to break the sounder barrier in 1947, the Douglas D-558, the Bell X-5, the Mach 7 X-15A2, and many others. Color and B&W, 1 hour. #00V7354
